Bug 13162 – std.algorithm.group accepts immutable(char)[] but not immutable(ubyte)[]

void main() { import std.algorithm: group; import std.string: representation; immutable(char)[] a1 = "111000"; a1.group; // OK ubyte[] a2 = [1, 1, 1, 0, 0, 0]; a2.group; // OK immutable(ubyte)[] a3 = [1, 1, 1, 0, 0, 0]; a3.group; // Error a1.representation.group; // Error } dmd 2.066beta4 gives: ...\dmd2\src\phobos\std\algorithm.d(4031,13): Error: cannot modify struct this._current Tuple!(immutable(ubyte), uint) with immutable members test.d(9,7): Error: template instance std.algorithm.group!("a == b", immutable(ubyte)[]) error instantiating ...\dmd2\src\phobos\std\algorithm.d(4063,13): Error: cannot modify struct ret._current Tuple!(immutable(ubyte), uint) with immutable members ...\dmd2\src\phobos\std\algorithm.d(4070,1): Error: template instance std.algorithm.Group!("a == b", immutable(ubyte)[]) error instantiating test.d(9,7): instantiated from here: group!("a == b", immutable(ubyte)[])
